Hi all, I am having trouble with a work/course related issue. As part of a project assignment I have decided to research the failure of some of the roof structure members at my place of work. To do this I need to calculate the reactions forces in the roof supports, but some trusses have two supports and a large cantilever section in the middle, some have four supports & to make things more complicated the repaired roof has 6 supports. For the life of me I cannot figure out how to work out the reactions when there are more than two supports, I have gone through old coursework and trawled the net & books and cannot find any examples with more than two supports. Can anyone please help. See rough pic below.
